Black Shark Phone Cooler, Cell Phone Cooler FunCooler 3 Pro Radiator with Sleep Timer and Smart Fan Speed Settings Function for iOS/Android (2.63-3.46 Inches) Semiconductor Heatsink Cooling

I have an iPhone 14 promax, and I cannot believe how amazing this little fan is! My phone heats up rather quickly, even without a case, in the summer heat. I play Pokémon Go, and needed a cooling unit for the upcoming yearly GoFest that occurs each summer! Last year, I did not have one for my iPhone 12 promax, and my screen was constantly dark, in an attempt to cool down. Needless to say, it wasn’t the best gaming experience :/ I had my eye on a similar fan to this brand, however, it was very pricey. I peeked at the reviews for this one and thought I’d give it a shot. I’m SO glad I did! This product is simply incredible and packs a lot of power, effectively keeping my phone very comfortably cool, even in 90 degrees with humidity! Not once has my phone screen gone dark, since purchasing this product! I’ve been using this fan for about a month now, sometimes in the hottest mid-afternoon sun, and have even been out for up to 3 hours at a time! It’s never given me any issue whatsoever! I’m very excited to play GoFest this year, knowing I won’t be putting my phone at risk for heat damage and knowing I have a fantastic, reliable cooling fan for all day use! 10 STARS!!!

Very strong cooling performance. You can also connect to app to control how much cooling you want. However, it is a little bit heavy so give it a 4 star.

it’s been warm and my iPhone doesn’t charge well in warm weather. In the last few days I’ve used it while charging and the results have been surprisingly great 👍, I’ve used cold packs in the past and that helps to pass 80%, with this is goes beyond that and more in a short time. Highly recommend

Seems well made but I am very unhappy that the app has to be side loaded and is not in the app store. Seems like a major security risk.

Nice cooling device.... Whisper quiet. Cools my phone around 15°. No more slowing down or buffering.

I purchased the Black Shark FunCooler 3 Pro Radiator, receiving it late on October 9. Initially, I had high hopes, but I’m very disappointed. Since then, I’ve only used it around 10 times. While I initially checked out the light features on the app, I ultimately disabled them, as my main goal was to cool my iPhone XS Max during gaming to prevent overheating. Unfortunately, the fan has already stopped spinning entirely.The device is in perfect physical condition, and I’ve handled it carefully. However, the app is somewhat clunky (it requires Bluetooth each time), and I’ve faced an excessive number of firmware updates – almost every other use. For such a simple product, this seems unnecessary and inconvenient.The final frustration is the 15-day warranty, which is shockingly short for a device that should last much longer. It’s been less than a month, and I already need a replacement that I can’t afford. I expected much better quality and support, especially for something I purchased on Amazon to help cool my phone effectively.I wouldn’t recommend this product unless the company improves its reliability and provides reasonable support. Many customers don’t open items immediately, and a product like this should have a longer lifespan.

Porque me juego mobile temperatura 40, black shark funcooler 3 pro 🥶 este temperatura más menor 31-33°c muy bien

I play CODM for long periods of time and had started dropping frames when my phone got too hot. Now that I've been using this fan my phone doesn't overheat and I don't loose any performance during extended gaming sessions, even while charging phone and recording gameplay at the same time. For lighter CODM sessions, I just put it on between matches for a quick cool down.The app allows you to change between fan speeds and even has an adaptive mode (I use this the most) that adjusts the fan speed based on the temperature of the device.I would highly recommend this to anyone playing demanding mobile games for any length of time.Side tangent - The reason I have deducted one star is for a couple minor personal gripes over the cooling fan - it's a little bulky and you do start to notice the added weight over long periods of gaming. I don't mean that to imply that the device is heavy by any means, but just be aware it takes some getting used to. It seeming bulky may simply be due to the way I hold my phone for gaming, but it doesn't interfere with my gameplay on this particular device. If someone were using a smaller phone, it is something to be aware of.
